notifyStartReorder method
Notifies the AnimatedListView that a new reoder has begun.
The context
has to be provided to help AnimatedListView to locate the item
to be picked up for reordering.
The attributs dx
and dy
are the coordinates relative to the position of the item.
Use this method only if you have decided not to use the AnimatedSliverChildBuilderDelegate.addLongPressReorderable attribute or the LongPressReorderable widget (for example if you want to reorder using your custom drag handles).
This method could return false
indicating that the reordering cannot be started.
Implementation
bool notifyStartReorder(BuildContext context, double dx, double dy) {
assert(_debugAssertBinded());
return _interface!.notifyStartReorder(context, dx, dy);
}
